The lever 22 lies substantially horizontally and in rear of the uppermost drawer of the series, its other end bein positioned so that it may be engaged by a Eeveled portion 28 formed by extending rearwardly one of the guides 15 of the uppermost drawer 14. Of course, the invention is not limited to moving the operating lever 22 by the upper drawer 14.

It is apparent that, when the uppermost drawer 14 is moved to closed position, the beveled portion 28 thereon will engage the free end of the lever 22 and, through the spring 24, cause the elevation of the locking member 16.
